Scientists used machine learning to discover what they say could be a new way to speed up the process of breaking down plastic significantly, [*Vice* reports](<https://www.vice.com/en/article/akvm5b/scientists-discover-method-to-break-down-plastic-in-one-week-not-centuries>).

As detailed in a [new paper](<https://www.nature.com/articles/s41586-022-04599-z.epdf?sharing_token=pt-lyCfsVz-vWUg2UhEmHdRgN0jAjWel9jnR3ZoTv0PeM6vTlVbebxCLhUAccDhih8V4_cqS0rGjHMFDcwcLPr3TrEYHSIRWQPTlggBJssazfgarW-eAp6_n6IBzHJAINU80-AKubUPPe35E214flsXg_z5HQHrRT7w3GzJbISk44XIldkQQCvjJGQE-1pUwC6EyNVIRBZyfDRdBqB445g%3D%3D&tracking_referrer=www.vice.com>) published in the journal *Nature*, a research team from the University of Texas at Austin modified an enzyme to break down the individual components of polyethylene terephthalate (PET), a commonly used plastic that makes up a staggering 12 percent of global waste.

Impressively, the modified enzyme also reduced the amount of time it takes for the plastic to degrade from months to a just single week.

The process, called depolymerization, has the added benefit of allowing the broken down monomers to be reconstituted back into virgin PET plastic, a potentially revolutionary way of recycling the astronomical amounts of plastic waste we've accumulated.

That all depends, though, on figuring out a reliable and affordable way to scale up and industrialize the process.

## Virgin Plastic

The fact that PET plastic can be turned back into virgin plastic is a big deal.

"This has advantages over traditional belt recycling," Hal Alper, professor in chemical engineering and author on the paper, told *Vice*. "If you were to melt the plastic and then remold it, you'd start to lose the integrity of the plastic each round that you go through with recycling."

This new method, however, can be used to make "virgin PET plastic each and every time," Alper added.

We've known about enzymes that can break down plastics since at least 2005, according to *Vice*, but many of them only work under very specific conditions.

Fortunately, Alper and his team says the new enzyme works in a variety of different temperatures and pH levels.

The team now has the difficult task of finding a way to produce their enzyme affordably and at an industrial scale.

But before then, the researchers are planning to systematically try it out on the huge variety of different PET plastics that can be found piling up in landfills.

## Author
I've been at Futurism since 2017, where my role has evolved to encompass design, writing, and increasingly editing. I've always been fascinated by space exploration and advanced transportation, which I've leaned into by interviewing luminaries in those fields while closely following the dimensions of policy and regulation that allow next-generation projects to succeed -- or, sometimes, to fail. I'm also keenly interested in the effects of generative AI on society, policies, and democratic institutions, as well as clean energy, physics and biology, and the vagaries of tech leadership. My work for Futurism has been cited by publications including Ars Technica, Gizmodo, PC Magazine, Jalopnik, Fox News, and the New York Post. I spent my childhood living in locations including Manila, the Philippines, and Geneva, Switzerland, attended McGill University, and now live in Toronto, Canada. Before Futurism I worked at AskMen and a small photography studio. In my free time, I'm an avid gardener, foodie, and craft beer lover, as well as a maker of artisanal hot pepper sauces. I have a magnificent dog named Freida.
